Who is the founder of Black History Month?

I'm going to offer a little more context to the previous educator's excellent explanation.
Carter G. Woodson earned a Master's degree in history from the University of Chicago and a doctorate from Harvard in the same subject. Over the course of his studies, he noticed how black people were largely absent from American history, as though they had no place at all in shaping national events and policies. For Woodson, the problem was not only scholastic but personal. His parents, James and Anne Woodson, were born into slavery. His father served in the Union Army in 1864. His mother had watched her own mother and two younger siblings get sold on a slave auction block. She was adamant that her children educate themselves, so that they would be less vulnerable to future oppression.
In 1915, he and Jesse Moorland—an educator, minister, and community leader—founded the Association for the Study of Negro Life and History, which is now the Association for the Study of African-American Life and History (ASALH). The association remains dedicated to researching, promoting, and interpreting aspects of Black history, life, and culture. The organization also publishes a seasonal journal and has re-released Carter G. Woodson's best-known book, The Mis-Education of the Negro, which had been out of print for many years.

Carter G. Woodson is known as the "Father of Black History." An African American historian and writer, he earned a doctorate from Harvard, becoming only the second African American to do so. He authored more than thirty books over his career, with the Mis-Education of the Negro being one of his most well known books. Woodson is credited with starting "Negro History Week" in 1926. Communities, churches, and schools were encouraged to participate in the celebration of African American contributions to society. February was the chosen month since Abraham Lincoln and Frederick Douglass, both important figures in African American history, were born in February. While it began as a week-long celebration, "Negro History Week" expanded into Black History Month and was officially recognized by President Gerald Ford in 1976.
